DISCLAIMER: This story contains sci-fi themes involving quantum mechanics, CGDCT, borderline (or maybe not) Girl’s Love, and plot-relevant mature scenes that are safe for general audiences.

Follow Kairi Izumi—a quiet, eccentric, and somewhat conspicuous girl—who never felt like anything but an NPC in a story. Working behind the scenes, unnoticed by others, had always been part of her daily life, dwelling with medicine and toxins. So, it's no surprise she wasn't exactly turning heads.

But then, a peculiar quantum anomaly shatters her carefully constructed anonymity, thrusting her into a bewildering new spotlight. Suddenly, Kairi's unique knowledge of obscure chemicals becomes crucial for navigating bizarre, shifting realities. 

However, her sudden visibility attracts more than just newfound affection. 

Now, Kairi must navigate not only the quantum uncertainties and her blossoming relationship, but also a treacherous game of power where her unique position could either be a weapon or a target.
